Homing of mRNA-Modified Endothelial Progenitor Cells to Inflamed Endothelium

open access: yesPharmaceutics, 2022
Endothelial progenitor cells (EPCs) are one of the most important stem cells for the neovascularization of tissues damaged by ischemic diseases such as myocardial infarction, ischemic stroke, or critical limb ischemia.

Reciprocal relationships in collective flights of homing pigeons [PDF]

open access: yes, 2011
Collective motion of bird flocks can be explained via the hypothesis of many wrongs, and/or, a structured leadership mechanism. In pigeons, previous studies have shown that there is a well-defined hierarchical structure and certain specific individuals ...

The homing flight method to assess the effect of sublethal doses of plant protection products on the honey bee in field conditions: results of the ring tests and proposal of a new OECD TG

open access: yesJulius-Kühn-Archiv, 2020
The evaluation of the potential effects of plants protection products on honeybee behavior is considered as part of the risk assessment according to Regulation (EC) No 1107/2009 and the EFSA Guidance document (EFSA 2013).

Deriving Homing Sequences for Finite State Machines with Timed Guards

open access: yesМоделирование и анализ информационных систем, 2020
State identification is the well-known problem in the theory of Finite State Machines (FSM) where homing sequences (HS) are used for the identification of a current FSM state, and this fact is widely used in the area of software and hardware testing and ...

Multimodal Tracking of Hematopoietic Stem Cells from Young and Old Mice Labeled with Magnetic–Fluorescent Nanoparticles and Their Grafting by Bioluminescence in a Bone Marrow Transplant Model

open access: yesBiomedicines, 2021
This study proposes an innovative way to evaluate the homing and tracking of hematopoietic stem cells from young and old mice labeled with SPIONNIRF-Rh conjugated with two types of fluorophores (NIRF and Rhodamine), and their grafting by bioluminescence (

Flow Dynamics and HSPC Homing in Bone Marrow Microvessels

open access: yesCell Reports, 2017
Measurements of flow velocities at the level of individual arterial vessels and sinusoidal capillaries are crucial for understanding the dynamics of hematopoietic stem and progenitor cell homing in the bone marrow vasculature.

In utero exposure to cannabidiol disrupts select early-life behaviors in a sex-specific manner

open access: yesTranslational Psychiatry, 2022
Cannabidiol (CBD), one of the main components of cannabis, is generally considered safe. CBD crosses the placenta and its use during pregnancy is steadily increasing, the impact of gestational CBD’s effects on prenatal life and neurodevelopment are ...

Light-dependent magnetoreception in birds : increasing intensity of monochromatic light changes the nature of the response [PDF]

open access: yes, 2007
Background The Radical Pair model proposes that magnetoreception is a light-dependent process. Under low monochromatic light from the short-wavelength part of the visual spectrum, migratory birds show orientation in their migratory direction.

Circadian migrations of cave-dwelling crustaceans guided by their home chemical seascape

open access: yesFrontiers in Marine Science
Organisms release and detect molecules for defense, reproduction, feeding strategies and finding suitable habitats. For some migratory species, homing behavior could be related to the recognition of their home chemical fingerprint made of an assemblage ...

The effect of partiality and adaptivity on the complexity of FSM state identification problems

open access: yesТруды Института системного программирования РАН, 2018
State identification is a long standing problem in the area of Finite State Machine (FSM) based modeling and testing of discrete event systems. For the identification of the current state of the system, so-called homing and synchronizing experiments with
